iwitness has worked fine up until recently- now it appears NOT to switch between cameras. AHP shows a switch between 2 wireless cameras (goes from "on air" to "GO LIVE" and vice versa. but split screen shows same image in both (one live - one frozen) which ever camera I unplug the remaining one shows in both screens. It appears that the OFF command to "deselected" camera isn't being sent. I should see a frozen image of the camera assigned there,in the deselected screen- not a frozen image of the NOW selected camera.... any ideas? (Both cameras share same housecode and have adjacent numbers..C1,C2

the cameras and power supplies used are the XC18A's and XM13A's (I have eliminated the cameras as source of problem as they work individually) When I hook up just ONE camera in iWitness and click on GO LIVE, I get working video when I try to click on another camera button (different unit code) it should cause the first camera to shut down-and show a "frozen" image it does, but NOW it puts LIVE video from THAT channel on the NEW screen (even though I should get a blank image screen without a camera connected to second button) If I install the ONE camera on 2nd button I get exact same problem, perfect video on that channel- and problems with the others when I try to switch over. In AHP, all other commands are working properly. With Quad screen and just ONE camera connected- I assume I should show one video image and three blank screens....switching to another screen should show frozen image on that first screen and the rest should STILL remain blank (since only one camera connected).....but I get that LIVE image on new selected screen-even though it is a different unit code... any suggestions appreciated.

looks like the same problem I was having! to fix this i had to have each cam in a different sequence 1-4 & 5-8. I was using a cam anywere same as the anaconda on a videosender. As soon as I put one on c4 the other on c5 problem was even worse so I had to create macros for c4 & c5 when one was turned on it would turn the other off. hopefuly this will be fixed with the next update or maybe thats the only way to add a video sender into the mix.

Just wanted to let everyone know I got my problem resolved. I first ruled out cameras as the cause by testing each one separately through a dedicated video monitor- I also ruled out video sender because this was able to handle the 4 cameras (sequential unit codes) and it switched through the 4 without any other images bleeding through.... then a single camera was hooked up to the video/USB interface through computer and everything was fine- when a second camera was added, the origional problem returned..! This pointed to "software" issues.... a re- install on iwitness seems to have cured things. I only wish I knew the cause...I'll try and keep track of things for awhile until i'm confident this won't happen again. If it does, at least i'll have some additional info to pass on.

Tuiceman, My problem seemed a bit different then yours, in that mine wasn't a sequential order issue- it was one where the selected camera would show LIVE video in one 1/4 of the quad screen and a "frozen" image of that SAME camera in another window (where it should have shown a frozen image of the camera assigned to that quadrant) if I didn't have all 4 cameras connected- I should have shown a blank screen for that (1/4) and NOT a frozen image of a camera that wasn't ever connected to that quadrant. 2 cameras connected to the "split quad screen" should never show more then 2 images (1 live one and one "frozen" image from 2nd camera) unused quads should remain blank.. in MY case, they didn't. sorry if this confuses anyone! It did me!

mine showed frozen pics of the video sender in all 3 of the boxes and live video in the proper one if I had 4 cams configured I had tested this when I was trying to nail down the problem. The only way I could cure this was having macros with the same address as the cams turn the other off. this was in XP as well as 98se. I never tried to put both cams back into the same grouping as someone had posted a bug when one cam was turned of all in that group were turned off. maybe that bug was patched I haven't checked.

If you are in the 4-camera split window, it should show stills from the non-active cameras, and live video from the current camera. If the timing between switching and grabbing an image is off, that could result in an image from one camera being displayed in the window of another.

Not switching at all is a different problem. If that happens, it would be good to determine if AHP/iWitness is sending a command to switch cameras. It should be logged in the Activity Monitor if it is. For troubleshooting, you could also set a lamp or appliance module to the same address as a camera to see if a signal is getting out.

Another thing to keep in mind: for XCam2 camera, AHP only sends On commands to switch if they're in the same camera group (1-4, 5-8, 9-12, 13-16). The reason for this is that the power supplies for the cameras have a built in functions to make switching faster -- if a camera set to A2 sees an A1 On command, it turns itself off. If the command isn't getting to the camera, it could be that the camera isn't turning itself off, leaving you with a mixed signal, or maybe video from only one camera.

Thanks x10 ! I had already swapped cameras with appliance modules to test for signals as you mentioned and saw the signals were going out (verified by activity monitor) everything worked fine with a single camera- it was only when I had two or more cameras installed and tried to switch between them that problem popped up. I have to assume a "timing" problem as you suggested because I WAS seeing the wrong "frozen" images in the wrong windows- anyhow, as mentioned, a reinstall on iwitness cleared everything up - for now. Thanks again!
